Django 1.11 can't get static files to work locally
I know there are a ton of similar questions, but I can't get it to work with any of the other answers.

It fails to serve. What am I missing? I've done these type of settings a ton of times before but for some reason on this project I just can't get it working with Django 1.11. -
How to limit the actions of a user in django CBV
I've got a theoretical question. For example I've got 2 blogs of 2 users. When I'm logged in as a first user I can see posts of the second user, but not only see but also update them and delete them. The same holds true to the second user which can delete and update the posts of the first user. What should i do in django class base view so that the first user can only edit and delete his own posts but not the posts of other users. I've come across request.user == post.user check in function based view. But what are the solutions for class based views. Thank you. -

Django Forms - how to check in __INIT__ method whether request.POST was provided
After two years of experience with Django forms, I ran into the following dilemma related to __init__ method: I have a Django form definition as follows: class MyForm(forms.ModelForm): def __init__(self, *args, **kwargs): self.user = kwargs.pop('user') super(MyForm, self).__init__(*args, **kwargs) if not MyModel.objects.filter(user = self.user).exists(): self.fields['field_1'].widget = forms.HiddenInput() self.fields['field_2'].widget.attrs['placeholder'] = 'Enter value' This code is ok if I initialize the form like this: my_form = MyForm() However, the problem arises when I try to save user input in the following way: my_form = MyForm(request.POST) My point is that I do not want to waste code execution time for setting placeholder property or deciding upon whether some field should be hidden or not AFTER the user has already submitted form. My concern is that maybe that's because I misuse __init__ method? Is there any way to check whether request.POST parameter has been provided? And if yes, is it considered best-practice to perform this check and do thinks like settings placeholder, initial values, etc. only if request.POST is not provided? -

Django _get_pk_val() returns None while pk exists
I use Python, Django, djongo and MongoDB. I've created a simple model and want to save and delete documents from my webpage. I manage to save them (checked in DB) with _id being ObjectID type. But when I try to delete them I have AssertionError (object can't be deleted because its id attribute is set to None). For document d I've printed pk by d.pk and got a correct value, but when I run d._get_pk_val() output is None. Do you know how to let Django know the primary key? I've tried to assign pk in the model by _id = models.AutoField(primary_key=True) but then _id is still of an ObjectID type, but delete() expect it to be int() and fail with an error (int() argument must be a string or a number, not ObjectID). My model: class DevList(models.Model): dev_num = models.CharField(max_length = 200) dev_name = models.CharField(max_length = 200) dev_descr = models.CharField(max_length = 200) dev_type = models.CharField(max_length = 200) And my views use simple d.save() and d.delete() functions.
